What Is Schizophrenia?

Schizophrenia is a mental disorder that affects 1% of the world's population. It causes horrible symptoms with negative mental, behavioral and speech effects. People with schizophrenia find it difficult to tell the difference between real and unreal experiences, have trouble thinking logically, and typically have abnormal emotional responses and social behaviors. Schizophrenia is not a split-personality disorder.

Causes

Genetic
Schizophrenia "runs in the family". People with close relatives who are affected are at a higher risk of developing schizophrenia. A persons risk is highest if they have a twin who has schizophrenia. If one twin is affected, there is a 40-50% chance the other twin will have schizophrenia too. The child of a patient has a 10% risk, second highest compared to the general populations 1%. external image alteredbrain.jpg

Scientific research suggests that chromosomes 6 and 13 can increase susceptibility. This theory is unproven.

Brain Development
Schizophrenia is caused by a chemical imbalance of dopamine in the brain. Physical abnormalities in the brain are also possible causes. Such abnormalities include enlarged ventricles (fluid-filled cavities in the brain) and decreased size of certain regions of the brain. Developmental neurobiologists funded by the National Institute of Mental Health (NIMH) have found that schizophrenia may surround abnormal connections that occur during fetal development.

Diagnosis

The DSM-IV-TR is used mostly in the United States and the ICD-10 is used mostly in Europe. According to the DSM-IV-TR, thrre are 3 diagnostic criteria that must be met to be diagnosed with schizophrenia.
1) Characteristic Symptoms: Two or more of the following symptoms in a one month period.
  • Delusions
  • Hallucinations
  • Disorganized Speech (if it substantially impairs communication)
  • Grossly Disorganized Behavior
  • Negative Symptoms--lack of or decline in emotional responses, speech or motivation

2) Social/Occupational Dysfunction

3) Duration: Combination of symptoms and social/occupational dysfunction for at least six months.

Treatment

Anti-psychotic medications can reduce symptoms and help a patient function more efficiently. Medication has been most effective in treating delusions and hallucinations.

Rehabilitation
There are many rehabilitation programs that include counseling, management skills training and social skills training as part of their treatment. These are especially helpful for discharged patients (not in a mental health facility).

Psychotherapy
One-on-one discussions between the patient and a mental health professional have been shown to be effective. For a patient, it may be helpful to share their personal experiences. The idea is that by talking about it, they might be able to learn about and even understand their problem.

Unfortunately, many patients are forced to go without any proper treatment because daily medications and consistent therapy is very expensive.
